-= Next Generation DC Readout Notes =
 * Put the resistors on the PD block, not the nipple.
 * Wider separation for the PDs so the ghost beam can get wedged out.
 * Black glass ring around the PD cans to catch the 1st ghost beam.
 * Black glass dumps all over the place for the leak throughs.  Optic mounts should have their own dumps.
 * Don't use any of the Piezo-Jena crap.
 * Don't use copper for the OMC body. All fused-silica, all the time.
 * Don't use a teensy mirror in the OMC. Calculate the needed resonant frequency.
 * Make both curved mirrors on a OMMT movable? And Bigger?
 * always draw ALL the dogs for EVERYTHING
 * CVI mirrors coated for 45P don't get better than ~98% reflectivity
 * Is it OK to change to use a fused silica baseplate with optically contacted mirrors?
